There are no real benefits to circ'ing. the cleanliness thing is a myth. a man who doesn't bathe properly is going to be dirty regardless of the status of his penis.

as far as cleaning an intact baby, you wipe it like a finger, no retraction ever. The foreskin is fused to the glans during infancy, retraction is painful and can cause infections.

Sorry if this is TMI, but my DH is intact. He has never had an infection and he isn't dirty or smelly. during bathing, he just retracts his foreskin and cleans and any other man would. the time difference for an adult male is literally a split second.
